I wonder if you could put a bar under the jig , say under the trigger hole, and the front part of the mag opening, run a bolt thru the holes to either go thru the bars, or thread them and use them to pull the flat down into the jig, at the very least it would put pressure on the flat so it would stay centered starting into the bending movement ?
This is the first jig that I have understood so I will have to make one----that means another kit, will it ever stop??????????????????

My friend beefed up the jig using 3" angle and made it longer so we could add a bolt past the front and back of the 1/4 inch bar stock to give more support to the front and rear of the flat. He also made a jig of angle iron to bend the rails first. Really added alot of stability during the bending process. He has a press and that helped alot! We did 3 last night that came out excellent.

I'm in the process of making one of these jigs - when I'm finished, I'll let you know. I'm concidering making some triangular shaped peices and having them welded in the middle where you described the problem with bowing. Also, I believe that the original called for using 1/4" angle - the extra thicknes might make a diference. BTW, I like the 'Busa signature pic - I have a '01 with a little work done to it. Great minds think alike .

the reason i ask is because I used 4" x 3/8" angle iron (big fu#kin' stuff) in only supported it at the ends with (3) - 3/8" bolts on each side.

My first attempt at bending a flat showed evidence of the jig bowing in the middle causing the middle of the receiver to be slightly wider than the front and back closest to the bolts.

I have since added support 3/8" bolts throughout the jig (slightly below where the male die bottoms out) and have had perfect bends.

Just wondering if anyone is noticing bowing with thinner, smaller angle iron.

I used 3/8 which is thicker than the plan on page one (1/4). That's why i had concerns of bowing. my stupid jig weighs 25-30 lbs. it's solid, but i can't sell it b/c i couldn't afford to ship the damn thing.

I'll have to come clean. I'm a wannabe busa owner. i have a Bandit 1200 but want to step up to a busa once i get some bills paid off.
